Abstract

A fundus camera with an OCT measurement module, in which, after the focusing objective, a mirror switches the light to be detected either to the OCT measurement module or an image detector. This design also renders it possible to carry out a method for improved focusing in order to improve the recording quality of the individual modalities. Furthermore, the multimodal measuring instrument distinguishes itself by an operating concept according to the invention. Such combination instruments are advantageous in that, as a result of the reduction from two instruments to one, less space is required than in the case of two separate instruments. Furthermore, reseating of the patient is avoided if recordings or measurements of different modalities should be made for one and the same patient, as a result of which the procedures in the medical practices and clinics can be influenced positively.
